Space Environmental Testing of PEEK and PFA sample (ExHAM-PEEK) - 02.28.18
Spacecraft wiring and tubing must be able to withstand the extreme temperature fluctuations and radiation hazards of space, but the harsh environment of space can degrade these materials, potentially causing damage. Exposed Experiment Handrail Attachment Mechanism-polyetheretherketone (ExHAM-PEEK) tests two spacecraft wiring and tubing materials, polyetheretherketone (PEEK) and perfluoroalkoxy alkane (PFA), to study the environment’s long-term effects on their performance. Science Results for Everyone
Initiation of this investigation has been affected by the loss of the Orbital-3 launch vehicle and mission in October 2014.

Applications
Space Applications
PEEK and PFA are used in spacecraft because they are lightweight and easy to manufacture, but their ability to withstand the temperature and radiation extremes of space cannot be studied on the ground. This investigation exposes PEEK and PFA samples to the exterior of the International Space Station (ISS) to study whether they degrade in space. Results from this investigation contribute to development of improved wire insulators and tubing materials for spacecraft and satellites.
Earth Applications
PEEK and PFA are commonly used on Earth in a variety of industrial applications. PFA is used to distribute and store harsh chemicals, and PEEK is used to replace any metal materials to transport liquid. Understanding how the materials degrade in harsh environments benefits users in the medical, chemical and industrial industries who use these products in a wide range of settings.
